once it's shaking between 30 seconds to a minute and once it's over, things will fall and tip over. give it time to move around. of course, if there is danger coming to you, you want to move. so, picture these buildings. against the wall. will i go behind this wall? lean against it, cover my head? no. the pictures frames. if they come off and hit me on the top of the head, more injuries. be aware of that target. look behind you before you lean against the wall.
